MOSCOW. Aug 13 (Interfax) - International Atomic Energy Agency (IAEA) experts visited the Zaporozhye Nuclear Power Plant (NPP) following a fire at its cooling tower, but have been unable so far to draw definitive conclusions regarding its cause.
"The team has not been able to draw definitive conclusions on the basis of the findings and observations so far," the IAEA said in a statement.
The IAEA experts did not observe either tires or drone remains during the walkdown, it said.
The team observed burnt equipment and droplets of burnt plastic and fragments of fallen concrete distributed across the cold-water basin, it said. The experts also collected samples of debris, the statement said, adding "that there were no significant signs of disturbance of the debris, ash or soot located at the base of the cooling tower."
"The team conducted radiation monitoring in the area of the cooling towers and the reactors and confirmed no signs of elevated radiation levels," it said.
The IAEA said it would continue its analysis of the incident.
On Monday, Zaporozhye NPP Director Yury Chernichuk said the cooling tower's separation devices burned down as a result of a Ukrainian drone attack. The building was attacked by a drone, which flew in through the tower's top, he said.
Governor of the Zaporozhye region Yevgeny Balitsky said on Sunday evening that Ukrainian forces shelled Energodar, causing a fire at a cooling tower of the Zaporozhye NPP. Rosatom said, for its part, that two Ukrainian drones attacked the cooling tower.
